Scaling up projects, programs, and their impact involves expanding their scope, coverage, funding, and replication. This allows benefits to reach more people, but it requires overcoming challenges like limited budgets. Strategies include leveraging co-financing, mainstreaming into government programs, and helping smallholders organize collectively to gain influence and access markets and services. The goal of scaling up is to sustainably improve livelihoods at a wide scale. It works best by strengthening community institutions first and then linking smallholder groups to private sector partners and financing sources. With the right models and incentives, scaling up can bridge the viability gap between what communities and the private sector can support alone.
